Infrared Intrinsically Safe handheld programmer
Auto False-Echo Suppression
Self-calibration

Capacitance

Our unique inverse frequency shift approach to capacitance technology ensures accurate, reliable, and repeatable measurement, even in dusty, turbulent, and vaporous environments, or in situations with product buildup. Because even a small level change creates a large change in frequency, our instruments provide better resolution and consistently outperform conventional devices.

WARREN CONTROLS 377 Float Cage

The 377 Float Cage can be utilized to open a 322 or 326 lever valve to supply intake liquid to a tank. When the liquid reaches the desired level the float cage closes the lever valve to accurately maintain the liquid at the desired level. Buoyancy of its internal float ball provides the force to actuate the valve.

WARREN CONTROLS 313 Overflow Trap

The 313 Overflow Trap traps and relieves excess condensate produced by tanks with steam blankets and by deaerators through its internal pilot without the steam blanket escaping. Buoyancy of its float ball provides force to actuate internal pilot operated single seat valve assembly to relieve condensate and overflow to drain. The overflow trap should be installed in an upright position.
